Use of solutions of atelocollagen and polyholosides, for example glycosaminoglycans, for the manufacture of microcapsules, microcapsules produced in this way, processes for the manufacture of such microcapsules and cosmetic, pharmaceutical or food compositions in which they are present

摘要

The invention relates to microcapsules with a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, and to processes for the manufacture of the said microcapsules.;According to the invention, the microcapsules comprise a mixed wall of crosslinked atelocollagen and polyholosides, for example glycosaminoglycans, the propor­tion of polyholosides, for example glycosaminoglycans, relative to the atelocollagen preferably being between 18 and 50% by weight. These microcapsules can be manufac­tured either by a process involving interfacial cross­linking or by the extrusion of a laminar flow which is broken up by vibrations into individual droplets, which fall into a crosslinking bath.;These microcapsules are biocompatible by virtue of the presence of atelocollagen, which has most of the advantageous properties of collagen, namely a very low antigenicity and a perfect biodegradability. They are therefore particularly suitable for the manufacture of cosmetic, pharmaceutical or food compositions.
